Profile XB64 is a compact double acting / bi-directional composite piston seal used for media separation.

It consists of a low-friction PTFE sealing element, two elastomeric O-Ring energisers and a low-friction elastomeric media separator seal located in the PTFE sealing cap. The media separator allows the separation of two types of media, a fluid on one side and a gas on the other – situations normally encountered in piston accumulators.

The use of two energising O-Rings optimises the sealing contact points and helps to reduce gas permeation through the inside of the groove and O-Ring. Using the combination of a PTFE sealing element and the correct choice of elastomer parts, this product can be made suitable for a wide range of situations including low friction, high temperature or where aggressive chemical media is the main system fluid
